Previous research in the area of buyer strategies for choosing sellers in ecommerce markets has focused on frequent purchases. In this paper we present a reputation based buyer strategy for choosing sellers in a decentralized, open, uncertain, dynamic, and untrusted B2C ecommerce market for frequent and infrequent purchases. The buyer models the reputation of the seller after having purchased g...

Recent empirical research documents that an exogenous rise in government purchases in a given country triggers a persistent depreciation of its real exchange rate— which raises an important puzzle, as standard macro models predict an appreciation of the real exchange rate. This paper presents a simple model with limited international risk sharing that can account for the empirical real exchange...

Consider the problem of estimating the timing and magnitude of peak sales for a new consumer durable product which is infrequently purchased and initially has few replacement purchases (as compared to initial purchases) . In such a case typically the sales rate climbs to a peak over a period of years and then declines somewhat, with replacement purchases becoming a larger component of total sal...

I propose a framework in which consumers have biased beliefs about their future purchase probabilities, leading them to make unplanned purchases. Using this framework, I examine the phenomenon of below-cost pricing and the welfare effects of banning it. When the market is covered, a ban on below-cost pricing raises social surplus, although consumers need not gain—they are only guaranteed to ben...
